Ethyl acetate and ethanol production in thermotolerant K. marxianus CBS 6556. a Specific growth rates of K. marxianus CBS 6556 and S. cerevisiae BY4742 were determined by shake flask culturing at temperatures of 30, 37, 40, 45, and 48 °C. b Aerated bioreactor growth and glucose consumption of K. marxianus CBS 6556 at 60% dissolved oxygen and 37 °C. c K. marxianus CBS 6556 production of ethyl acetate and ethanol during the bioreactor experiments shown in b. Data points represent the arithmetic mean of three biological replicates, and the error bars represent the standard deviation
